STUDY ON IMPACT OF ECOLOGICAL GARDEN LANDSCAPE DESIGN ON ATMOSPHERIC PARTICULATE MATTER CHANGES

摘要

Air pollution is the single largest environmental health risk. It significantly impacts human life and the condition of ecosystems. One type of dangerous pollutant is particulate matter (PM). All of the countrie should take intensive actions to achieve the necessary standards of air quality. These actions should be aimed at reducing emissions on the one hand, and on the other, at reducing the PM concentrations in the air. This paper takes the ecological garden landscape as the research background, and analyzes the impact of ecological garden landscape design on the change of PM2.5. The experimental results show that different kinds of garden plants have different adsorption capacity per unit area, and the plants with the strongest PM2.5 adsorption capacity arc evergreen needles. Taking into account the green areas together with pollution sources in spatial planning can significantly support the effectiveness of air protection, and at the same time, can increase the comfort of life by providing a whole range of ecosystem services.
